Adherence to recommended preventive self‐care behaviours, like allergen avoidance and carrying emergency medication, are rarely assessed. Social Cognition Models (SCMs) have been successfully applied to a number of adherence‐related studies in disease conditions such as asthma and diabetes, but have not yet been applied to food allergy induced anaphylaxis.</p> <p> <italic> <bold>What does this study add?</bold> </italic> <list id="bjhp12033-list-0001" list-type="bullet"> <list-item> <p>This is the first large‐scale quantitative study of adherence behaviours in adolescents with food allergy.</p> </list-item> <list-item> <p>This is the first study to apply theoretical models to explain adherence in the adolescent food allergic population.</p> </list-item> <list-item> <p>This is the first application of both models to food allergy, and the first to compare the two models' measurement instruments.</p> </list-item> </list> </p> </sec> </abstract>
